  vee-validate文档使用说明
  1. 文档
    https://vee-validate.logaretm.com/v3/guide/forms.html#basic-example
  2. 下载
    npm i vee-validate
  3. 使用
    - 定义表单校验规则
      先要引入
      import { extend } from 'vee-validate';
      extend('规则名称', {
        validate(value) {
          // value就是校验的值
          return xxx; // 返回值true校验成功，反之校验失败
        },
        message: 'xxx' // 校验失败提示的错误信息
      });
    - 校验表单
      注册两个组件 ValidationObserver ValidationProvider
      <ValidationObserver v-slot="{ handleSubmit }">
        <form @submit.prevent="handleSubmit(onSubmit)">
          校验表单
            rules 表单校验规则
            v-slot="{ errors }" 通过作用域插槽得到校验失败的错误 errors
          <ValidationProvider rules="required|email" v-slot="{ errors }">
            <input v-model="email" type="email">
            <span>{{ errors[0] }}</span>
          </ValidationProvider> 
          ...
        </form>  
      </ValidationObserver>  
*/
  import { ValidationObserver, ValidationProvider } from "vee-validate";
  // 引入校验验证码的方法//引入注册的api
  import { reqSendCode,reqRegister } from "../../api/user";
  import "./validate";
  import { phoneReg } from "../../utils/regs";
  
  export default {
    name: "Register",
    data() {
      return {
        user: {
          phone: "",

          verify:false,
        },
      };
    },
    methods: {
      // 注册跳转
       async submit() {
        try {
        //console.log("表单校验触发了");
        // 解构要使用的三个参数
        const {phone,password,code} =this.user
        // 设计的时候传的什么参数，用的时候就怎么去用
         await reqRegister({phone,password,code})
        // 跳转到登录页面
        this.$router.history.push('/login')
          
        } catch (e) {
          console.log(e);
        }
      },
      //发送验证码
      // 注意:不会发送到手机上,服务器又不可见,所以验证码直接返回给客户端了(正常不会)
      async sendCode() {
        const code = await reqSendCode(this.user.phone);
        console.log(code);
      },
    },
    computed: {
      isDisabled() {
        return phoneReg.test(this.user.phone) ? false : true;
      },
    },
    // 注册vee-validate插件库的两个组件
    components: {
      ValidationObserver,
      ValidationProvider,
    },
